If you would like to add a preloader to your image show you have to check the corresponding check-box. The preloader is a little animation which will run on the screen until loading the image show. In the X and Y text fields you should write the distance (in pixels) between the top left corner and the preloader.
If you added a soundtrack to your image show (see the “Adding soundtrack” chapter to see how) you might probably want a sound control button. You can add it to your show by enabling it from here; it controls the sound like an ON/OFF flip-flop button - ON position and OFF position, represented by different images. Same as for the preloader, in the X and Y text fields you should write the distance (in pixels) between the top left corner and the sound control.
The last check-box enables a replay button. This button gives the viewer the possibility to see the show again, once the show is finished. The X and Y text fields work the same as for the previous controls.
